<p>EvoTears are a water-free, preservative-free eye drops which act to stabilise the tear film lipid layer, relieving symptoms associated with evaporative dry eye and meibomian gland dysfunction (MGD). </p> <p>Evaporative dry eyes are caused by an unstable or deficient lipid layer of the tear film (the top outer most layer) that affects almost 90% of dry eye patients. Despite this, only a small proportion of products address lipid layer issues. </p> <p>EvoTears offer the unique lipid layer replacement benefits of perfluorohexyloctane. </p> <p>This allows EvoTears to replace the function of the lipid layer, forming an outer shield over the surface of the tear film, reducing evaporation of the watery layer. </p> <ul> <li>Spreads easily due to low surface tension properties. </li> <li>Replaces the outer lipid layer of the tear film. </li> <li>Helps to indirectly re-establish the tear film's watery layer by preventing its evaporation. </li> <li>Increases tear film thickness, as well as lipid layer thickness, over time. </li> <li>Preservative & phosphate free. </li> </ul>
